PROCEDURA PER LA VERIFICA DELLA CUBATURA Far smontare il motore dal telaio Attendere che sia a temperatura ambiente Fare smontare la testata per verificare la sporgenza della candela all interno della cupola della camera di combustione Fare smontare la candela ( verificare la quota del 18,5mm) Avvitare L INSERTO al posto della candela ( L inserto stretto sulla testata, non dovrà oltrepassare la parte superiore della camera di combustione. Esso dovrà essere fissato sulla testata nello stesso ed identico modo come era fissata la candela di 18,5mm) Rendere stagno con l aiuto di grasso la parte superiore del pistone e la periferica del cilindro Mettere il pistone a punto morto superiore e bloccare l albero motore Asciugare accuratamente l eccedenza di grasso Assicurarsi che il motore sia in piano Fare rimontare la testata e stringerla alla coppia di serraggio definita dal Costruttore Con una buretta di laboratorio graduata ( meccanica o elettronica) riempire la camera di combustione ( con una miscela del 50% di olio utilizzato per fare la miscela e il 50% di carburante) fino a quando il liquido rasenta il bordo superiore dell inserto Il volume allora misurato dovrà corrispondere al volume minimo della camera di combustione indicato nella scheda di identificazione del motore stesso. PROCEDURE USED TO MEASURE THE VOLUME OF THE COMBUSTION CHAMBER Disassemble the engine from the chassis Wait until the temperature is ambient temperature Disassemble the cylinder head in order to verify the projection of the sparking plug inside the combustion chamber. Disassemble the sparking plug ( verify the height of 18,5mm) Screw the INSERT at the place of the sparking plug (The insert on the cylinder head has not to overpass the superior part of the combustion chamber. It has to be fixed on the cylinder head in the same way the sparking plug of 18,5mm was fixed) Make it air tight and water tight with grease the upper part of the piston and the cylinder device Raise up the piston and stop the crankshaft Dry up the excess of grease Be sure that the engine is on a flat surface Move up the cylinder head and tighten it to clamping forces defined by the manufacturer. Fill up the combustion chamber (with a mixture composed by 50% of the oil used to make the mixture and the 50% of the fuel) using a graduated burette (mechanical or electrical) until the upper border of the insert. The measured volume must show a value which is complying with the minimum combustion chamber volume set on the engine identification sheet concerned. - pag. 6 - www.vortex-rok.com
